AIR AND AUXILIARY PUMP ARRANGEMENT FOR MARINE DIESEL MOTORS.

Application filed May 21,

To all "whom it may concern:

Be it known that I. Pnosrna LORANGE,

a German citizen. and residing at Mannheim-Feudenheim. Germany. have invented certain new and useful Improvements in an Air and Auxiliarv Pump Arrangement for Marine Diesel Motors (for which I ha e made application for patent in Germany on May 30th. 1923. No. 81590), of which the following is a specification.

As known. the length of marine engines is kept as short as possible to gain a larger hold for the cargo. Thus. generally. the air pumps required for manoeuvring and the like are arranged separately from the main engines between engines and ships side. in which case. however. a separate motor 1s required for drlving sa1d pumps whereby the 7} plant becomes rather expensive. .With crosshead engines said drawback 1s avoided by driving the air pumps as well as the cooling and bilge pumps by radius hnks from the eross-head in a way known in the art. The

provision of such radius links makes the gearing very compli- 1924. Serial No. 714.964.

Owing to two adjacent engine cvlii'u'lers working always on a common radius link. sutiicient space is left between the supports 09 for locating the air pump i and thermoling and bilge pump a verticallvabovc and below a point of the radius link between its fulcrum and its point of connection with the engine connection rod respectively. said pumps being directly driven from said radius link in upward and downward direction respectively.

Thereby. it is possible to locate all the pumps in proximitv to the engine middle so that the space required on board by the main en ines is fully utilized.

What I claim. is:

In an air and auxiliary pump arrangement for marine Diesel motors: the combination with two adjacent engine cylinders and an engine connection rod: of a ommon radius link by which said connection rod is adapted to be driven from said cylinders. and an air pump and a cooling and bilge pump respectively located vertically above and below a point on said radius link be tween its fulcrum and its point of connection with said engine connection rod and adapted to be directly driven from said radius link in upward and downward direction respectively. substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

PROSPER LORANGE.
